HOLDBACK FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 485,550, dated November 1, 1892.

Application filed April 26,1892. Serial 110.430,699. (N0 model.)

To all whom it may concern:

Be it known that "we, EDWARD W. LANGER and ROBERT PETERSON, citizens of the United States, residing at Diamond Bluff, in the county of Pierce and State of Wisconsin, have invented new and useful Improvements in Holdback Attachments for Thills, of which the following is a specification.

This invention has for its object to provide a novel, simple, efficient, ahd economical hold-v back attachment for thills, which is susceptible of quick and convenient operation to engage or release the breech-strap and when engaged therewith eectually prevents disengagement of the strap until the latter is intentionally released from the locking-pin constituting a part of the attachment.

To accomplish this object our invention consists in a holdback attachment for thills, composed of a base-plate having screw-holes for screwing it to a thill, a pendent pin and lateral ears provided with a pivot-pin, a jaw or lever having a pin-hole at one end, a handle portion at the opposite end and provided intermediate at its ends with pendent ears mounted on the pivot-pin, and a spring vcarried by the pivot-pin and acting upon the jaw or lever to press its pin-hole in engagement with the pin on the base-plate for holding a breeching-strap in engagement with such pin.

The invention is illustrated by the accom`- vpanying drawings, in Which-- Figure l is a side elevation showing a p0rtion of a thill with my improved holdback attachment applied thereto. Fig. 2 is a longi tudinal central sectional view of the same. Fig. 3 is a detail perspective view of the baseplate. Fig. 4 is a detail perspective view of the oscillating jaw or lever, and Fig. 5 is a detail perspective view of the jaw or lever pivot and the spring for holding the jaw or lever in engagement with the pin on the base-plate.

In order to enable those skilled in the art to make and use our invention, we will now describe the same in detail, referring to. the drawings, whereinHz The numeral 1 indicates a thill, and 2 the base-plate, of the holdback attachment. This base-plate is provided at each extremity with a screw-hole 3 for the passage of a screw by which to rigidly secure the attachment to the thill. The baseplate is formed centrally between its extremities with a pair of pendent ears 4, through which extends a transverse pivot-pin 5, and the oscillating jaw or lever 6 55 is also formed centrally between its extremities with a pair of pendent ears 7, located between the ears 4 of the base-plate and mounted on the pivot-pin 5. By this construction of the jaw or lever we are enabled to mount it on 6o the pivot-pin and at the same time place the clamping portion 8 of the jaw or lever in close proximity to and parallel with the base-plate of the attachment in such manner that a holdback-strap 9 can be passed lengthwise 65 between the base-plate and the jaw or lever,

as in Fig. 1, andthe clamping portion 8 of the jaw orlever will lie squarely against the strap. The front portion of the base-plate 2 is provided with an attached pendent pin 10, adapt- 7o ed to pass through any one of a row of perforations 12 in the holdbackfastrap 9.

The forward extremity of the clamping por tion 8 of the oscillating jaw or lever 6 is provided with a pinhole 13 for receiving the pin 75 10 in such manner that after the holdbackstrap 9 is engaged with the pin the latter can be caused to pass through a pin-hole in the clamping portion 8 of the jaw or lever, so that the latter retains the holdback-strap in posi- 8o tive engagement with the pin. The pivotpin of the jaw or lever is provided with a yoke or bow shaped spring 14, having its extremities turned round the pivot-pin in the form of spiral coils l5 and engaged with the 85 ears 4, so that the yoke or bow shaped portion 14 of the spring will constantly bear against the clamping portion 8 of the jaw or lever and .force it toward the base-plate for the purpose of eectuallyretaining the holdback-strap in 9o engagement with the pin.

- The particular construction of the jaw or lever with its pendent ears 7 and a baseplate having the pendent ears 4 and the pivotpin 5 are features which render this attach- 95 ment useful for retaining the breeching-strap,

in that the main clamping portion of the jaw or lever is arranged relatively to the base plate to provide for the passage of the strap and at the same time press the latter against roo the base-plate for holding it in engagement with the pin. The handle portion 16 of the nweclaim is i jaw or lever is curved downward away `from the base-plate, and this handlel portion constitutes one extremity of the jaw or lever, whereby the latter can be oscillated on the pivot-pin, which is located about centrally between `the extremities of the jaw orlever.

`The' holdback attachment constructed as described -is simple, eiiicient, and economical, and by the oscillating character of the jaw or lever it is possible to quickly` and conveniently introduce the breechng-strap and hold it in positive engagement with the pin on the base-plate, while a slight pressure on the handle portion 16 of the jaw orf lever will instantly free its pin-holey from the pinland thereby enable the breeching-strap to be disengaged from such pin and removed from the holdback attachment.

Having thus describedourinven-Lion, what A holdback attachment for thills, Composed of a base-plate having screw-holes 3 for screwingit to a thill, a pendent pin lO, and

. andprovided intermediate-its ends with pendont ears?, mounted on the pivot-pin, and a spring 14, carried by the `pivot-pin and acting upon the jaw or lever to press its pinholein-engagenlent with the pin on the baseplate for holdingabreeching-strap in engagement with such pin, substantially as described.

In testimony whereof we have hereunto set i our hands in presence of two subscribing wituesses.
